'Secrets of Penthouse' unfolds the rise and fall of Bob Guccione's porn empire

Having carved out a niche in vaguely sleazy "Secrets of" docuseries beginning with Hugh Hefner and Playboy, A&E finds an ideal and perhaps inevitable playground for the franchise with "Secrets of Penthouse," which basically serves as a four-part biography of the magazine's founder, Bob Guccione. As trashy as one might expect, it's also a rise-and-fall story, told heavily through Guccione's children, about an empire built and lost.
